OBJECTIVE:To establish a method for simultaneous determination of the contents of ligustroflavone,specnuezhe-nide,demethylwedelolactone and wedelolactone in Zibu ganshen pill. METHODS:Dual-wavelength HPLC was performed on the column of Elite C18 with mobile phase of acetonitrile-0.5%acetic acid(gradient elution)at flow rate of 0.9 ml/min,column temper-ature was 25 ℃,detection wavelengths were 224 nm(0-30 min) and 351 nm (30-50 min),and the injection volume was 20 μl. RESULTS:The linear range was 6.75-135.00μg/ml(r=0.999 5)for ligustroflavone,6.54-130.80μg/ml(r=0.999 8)for specnuezhe-nide,4.90-98.00μg/ml(r=0.999 4)for demethylwedelolactone and 6.42-128.40μg/ml(r=0.999 6)for wedelolactone;RSDs of pre-cision,stability and reproducibility tests were no more than 1.25%;average recoveries were 96.15%-99.96%(RSD<2%,n=6). CONCLUSIONS:The method is rapid,sensitive and accurate,and can be used for the contents determination of ligustroflavone, specnuezhenide,demethylwedelolactone and wedelolactone in Zibu ganshen pill.

Objective To observe the effects of Hedan tablet on cytokines and oxidation factors in APOE-/-mouse, and to explore its effect on atherosclerosis and to explore its behind mechanism. Methods APOE-/-mice (n=50) were randomly divided into control group, model group, low dose Hedan tablet treatment group, high dose Hedan tablet treatment group and simvastatin treatment group. Mice in control group were given normal feed while mice in other groups were fed with high cho?lesterol diet. Hedan or Simvastatin was administrated intra-gastrically while normal saline was given to model group in the same route. After 12 weeks, mice were sacrificed to observe the mRNA level of tumor necrosis factor-α(TNF-αmRNA) in aorta by RT-PCR. Mean while, serum levels of interleukin-1 (IL-1), interleukin-10 (IL-10), malonaldehyde (MDA) and su?peroxide dismutase (SOD) were determined in different groups. Results Compared with control group, TNF-αmRNA tran?scription level as well as serum levels of IL-1 and MDA significantly increase while serum levels of IL-10 and SOD de?creased remarkably in model group, (P<0.01). Compared with model group, mRNA levels of TNF-αas well as serum levels of IL-1 and MDA were significantly decreased while serum levels of IL-10, SOD were greatly increased in low dose and high dose Hedan tablet treatment groups as well as in simvastatin treatment group (P<0.01). Conclusion Hedan tablet inhibit the formation of atherosclerosis through its anti-oxidation role and anti-inflammation role.

Objective To explore the relationship of the polymorphism of E-selectin gene A561C and essential hypertension (EH) among Chinese people. Methods Genotypes of E-selectin were analyzed in 95 EH patients with age ≤70 and 101 normal controls people matched in age and gender by polymerase chain reaction-restriction fragment length polymorphism ( PCR-RFLP). Serum levels of lipid, glucose, urea and creatinine were measured by biochemical techniques. Plasma soluble E-selectin were measured by enzyme-linked immunosorbent assay(ELISA). Results The frequency of E-selection genotypes AA, AC and CC in EH group were significantly higher than normal group (P

Objective To explore the relationship among social support, postpartum depression and quality of life of puerperal women. Methods A total of 348 puerperal women were investigated with Postnatal Social Support Questionnaire,Edinburgh Postnatal Depression Scale (EPDS) and WHO Quality of Life-BREF (WHOQOL-BREF). Results Pearson correlation analysis showed that there was a significant positive correlation between social support and the quality of life (r=0.483, P < 0.01), and a significant negative correlation to postpartum depression (r=-0.243, P < 0.01),and a significant negative correlation between postpartum depression and quality of life (r=-0.408, P<0.01). Intermediary effect of postpartum depression was tested. Conclusions A good social support system is benefit to improve depression scores for EPDS, and promote the life quality in puerperal women.

Objective:This work aims to investigate diallyl disulfide (DADS) inhibition of cell migration and invasion in human colon cancer SW480 cells through the Rac1-ADF/cofilin1 pathway. Methods:The potential of cell migration and invasion was examined by scratch healing assay and transwell membrane assay. The expression of Rac1-ADF/cofilin1 pathway was detected by RT-PCR and Western blot. Results:After the SW480 cells were treated with 40 and 50 mg·L-1 of DADS for 24 h, the number of transmembrane cells through the Matrigel obviously decreased by 57.12%and 64.59%, respectively (P<0.05). After cell treatment for 48 h, the cell migration rates were 23.23%and 12.87%, which were significantly lower compared with the control group (75.86%;P<0.05). After the cells were treated with 45 mg·L-1 of DADS for 24 and 48 h, the expression of Rac1, Rock1, PAK1, LIMK1, and destrin mRNA respectively decreased compared with the control group (P<0.05). However, no significant difference was observed in the expression of cofilin1 mRNA (P>0.05). After the treatment with 45 mg·L-1 of DADS for 6, 12, 24, and 48 h, the expression of Rac1, Rock1, PAK1, LIMK1, and Destrin proteins respectively decreased in a time-dependent manner compared with the control group (P<0.05). However, no significant differences were observed in the expression of the cofilin1 protein (P>0.05). Moreover, the expression of p-LIMK1 and p-cofilin1 notably decreased in a time-dependent manner (P<0.05). Conclusion:DADS inhibits cell migration and invasion, which is related to the down-regulation of Rac1, Rock1, PAK1, LIMK1, p-LIMK1, p-cofilin1, and destrin through the Rac1-ADF/cofilin1 pathway.

Objective To discuss the differences of the types of cerebral palsy and the comorbidity between premature and full-term infants. Methods 233 children with cerebral palsy were divided into premature group (n=98) and full-term group (n=125). The types of cerebral palsy and the complications were analyzed. Results The high risk factors were low birth weight, jaundice, asphyxia, intracranial hemorrhage and cord around neck in sequence in the premature group, and were asphyxia, jaundice, fetal distress, intracranial hemorrhage and intrauterine infection in sequence in the full-term group. Besides auditory handicap. The frequency of spastic diplegia was higher in the premature group than in the full-term group (P<0.001), and the incidence of spastic hemiplegia was higher in the full-term group than in the premature group (P<0.01). There was no significant difference in dysgnosia, epilepsy and visual disturbance (P>0.05), but auditory handicap (P<0.05) between 2 groups. Conclusion The main clinical types of premature and full-term children with cerebral palsy were spastic diplegia and spastic hemiplegia respectively. The prevalence of auditory handicap was higher in preterm children

Objective To investigate the characteristic of vastus lateralis (VL) and vastus medialis (VMO) during the Taijiquan exercise with surface electromyography (EMG). Methods 15 healthy adults were collected their median frequency (MF), mean power frequency (MPF), zero crossing rate (ZCR), averaged EMG (AEMG) of bilateral VL and VMO when they maintained 5 Taijiquan typical posture. Results The differences were not significant in all those indexes between VL and VMO during the postures of Baihe Liangchi and Jinji Duli, and were significant during the postures of Louxi Aobu, Shizi Tui, Pubu (P<0.05), the VL's indexes were less. Compared with the maximum voluntary contraction, Taijiquan was the lower loaded, and more slow muscle fibers could be recruited. Conclusion Taijiquan is a lower loaded exercise, and more slow muscle fibers can be recruited, especially in the VMO in some actions.
